Kim Kardashian, Kourtney Kardashian, Khloe Kardashian head out of their hotel to promote their new book in NYC, Nov. 29, 2010.

The recently reunited pair heads south for Thanksgiving, enjoying a sexy vacation with friends!

It looks like after a brief break, baseball star Alex Rodriguez and Cameron Diaz are once again inseparable! The gorgeous pair was spotted last week working out and soaking up some rays in Miami and evidently decided to keep the vacation going with a Thanksgiving trip to sunny Mexico!

As we previously reported, Alex missed Cameron after their split and, after a whole lot of pleading, convinced her to get back with him. The two now look closer than ever, Cameron,38, in her bikini and Alex, 35, in his trunks, as they cool off at their exclusive resort.

What do you think about Cameron and A-Rod’s reunion HollywoodLifers? Is it for real this time or will it fizzle out again?
